Vertigo /ˈvɜrtɨɡoʊ/ (from the Latin vertō "a whirling or spinning movement"[1]) is a subtype of dizziness in which a patient inappropriately experiences theperception of motion (usually a spinning motion) due to dysfunction of the vestibular system.[2][3][4] It is often associated with nausea and vomiting as well as abalance disorder, causing difficulties with standing or walking. There are three types of vertigo. The first is known as objective[5][6] and describes when the patient has the sensation that objects in the environment are moving. The second type of vertigo is known as subjective[5][6] and refers to when the patient feels as if he or she is moving. The third type is known as pseudovertigo,[7] an intensive sensation of rotation inside the patient's head. While this classification appears in textbooks, it has little to do with the pathophysiology or treatment of vertigo.

The condition was first discovered by Irmin Roberts, a Paramount second-unit cameraman, and was famously researched by Alfred Hitchcock.
